Analizador de paquetes de la Sala de juegos

En esta página, se explica cómo usar el analizador de paquetes de la Sala de juegos.

Instrucciones

El analizador de paquetes de la Sala de juegos se puede ejecutar en un paquete de juegos varias validaciones en el paquete del juego antes de subir los recursos a Google Drive

Requisitos previos

• Instala Python 3.

Crea la secuencia de comandos

1. Identifica un directorio en tu máquina para crear la secuencia de comandos (ejemplo: ~/scripts).
2. Con el código de muestra proporcionado, crea un archivo en tu máquina. llamada playables_bundle_analyzer.py.

Ejecuta la secuencia de comandos para analizar el paquete de juego

1. Abre una ventana de terminal en tu máquina y navega al directorio que contiene la secuencia de comandos playables_bundle_analyzer.py.

2. Para ejecutar la secuencia de comandos, ejecuta este comando y reemplaza [GAME_DIRECTORY_PATH]. por la ruta de acceso real del directorio de tu paquete de juego:

   python3 playables_bundle_analyzer.py [GAME_DIRECTORY_PATH]
   

3. Se generará un informe de análisis de paquete en el directorio de secuencias de comandos. Si Se llamará playable_bundle_analysis_report.txt.

4. Consulta los requisitos de estabilidad y rendimiento para obtener más información. sobre el tamaño del paquete y el requisito de nombres de archivos.
